The outside diameter of the m2 bearings are to small. They aren't available with a 30mm inaide diameter.

Testfitted the M2 wheel. Belt is way too long. XB uses a 65T rear pully, the M2 a 61T. Both use a 27T front Pulley. Is de gearbox on the XB a different end ratio than te M2?

You will receive educated guesses here mostly from Buell owners. The M2 engine was mostly a stock xl 1200 mill from the Sportster assembly line. The XB was purpose built for Buell and had a major change in the rear engine mount and swing arm attachment point. The XB brings the swing arm pivot bolt closer to the rear of the transmission so the belt is much shorter.
If you weigh the sprockets with the belt it will be much heavier than the chain with the chain sprockets so the most flexible path is to go with chain final drive. This way the gearing can be altered to suit your needs. Typically US built bikes are geared too high for long runs on autobahn design roads.

You will spend a lot more than $300 trying to make that M2 wheel fit. Best bet is to suck it up and get the XB wheel and pulley tbh. Otherwise you would have to bore the M2 wheel's bearing races to accept the larger bearings and then still find a 65t rear pulley to fit the belt. No such thing as a 124t belt as far as I know, to utilize the stock pulley.

Too bad about putting a carb on it. Certainly doable, but I think it would be way cooler to put 07-up XL Delphi EFI on it and a Dynojet Power Vision, since you already have a crank sensor. That way you could also utilize the auto tune features.

Also, you may want to add a bit more clearance between the rear rocker box and shock mount. The motor moves a bit in vibration because of the isolator design, and if you ever have a rear isolator fail in particular, you will have some serious contact there. Also, the tab on the frame behind the shock needs to go as well, or it will hit and bind the shock. The shock moves back and forth a few inches during travel, because of the pitch and design. You will need to account for this during your fabrication process as well.

The wheel is being bored this week. I found a 65t pulley and i ordered the bearings and bushings. All for under 150 USD
